The Fluid Mechanics of Volcanic Eruptions Transient Jets of Multi-phase Fluids

本研究涉及多相流体超音速射流的流体动力学行为的实验研究以及在火山爆发理解中的应用。实验室类似物将允许对多相流体瞬态射流中质量、动量和能量的传递机制进行控制研究。将研究储层和排气口几何形状、颗粒载荷和相位变化的影响。研究了静水压力下储层减压过程中成核和沸腾的影响。

This research involving experimental studies of the fluid dynamic behavior of supersonic jets of multiphase fluids and applications to understanding explosive volcanic eruptions. Laboratory analogs will allow controlled study of the mechanisms of transport of mass, momentum, and energy in transient jets of multi-phase fluids. The influence of reservoir and vent geometry, particulate loading, and phase changes will be investigated. The effects of nucleation and boiling during decompression of resevoirs under hydrostatic pressure will be investigated.
